change xdata in my dxf
change xdata in my dxf
hi!
on my search for a way to change xdata in my dxf i抳e come across 搊ddbentmod?as a possible way, i hope, i might be dead wrong about this! so to get some understanding of this i抳e looked at the odamfcapp and found this section:
code:
try
{
oddbentmod(m_pobjectid,m_presbuf);
}
catch( const oderror& ex )
{
afxmessagebox(ex.description());
}when trying this in my own code i get the message box: 揘o interface? this exception is thrown if the passed in object cannot be opened in kforwrite mode. i can open in kforwrite mode the first time around but when i've changed data and comes back to below code section ( bedited = true ) i get my butt kicked.
code:
for (pblkiter->start(); ! pblkiter->done(); pblkiter->step())
{
// open the block
oddbblocktablerecordptr pblock = pblkiter->getrecordid().safeopenobject();
// get an entity iterator
oddbobjectiteratorptr pentiter = pblock->newiterator();
// for each entity in the block
for (; !pentiter->done(); pentiter->step())
{
oddbobjectid id = pentiter->objectid();
pent = id.safeopenobject(oddb::kforwrite);
odresbufptr podresbufptr = pent->xdata( "dxf_converter" );
if( !bedited )
{
pent->setxdata( xiter );
}
else
{
try
{
oddbentmod( id, podresbufptr);
}
catch( const oderror& ex )
{
afxmessagebox(ex.description());
}
}
}
}
if anyone knows about this kind of problems ( change xdata ) then please give me a hint. and again, i might be barking up the wrong tree here in more then one way?.
regards
kennet
no problem...sorry!
i guess i was a bit too hasty sending in above question. now when i looked back at my 損roblem?it really was no problem, it seems.
